Super Lightweight Rotor Assembly87-95 Turbo

Our Super Lightweight Rotor Assemblies for 1987-95 Turbo applications are machined lightened using a CNC (computer numerically controlled) mill. These Super lightweight Turbo rotor assemblies are based on the stock 1989-91 rotors (9.0:1 compression ratio). The initial weight of each rotor is approximately 9.7 pounds, and upon completion of the machining process the weight is reduced to approximately 8.7 pounds.

Years of experience have allowed our engineers to refine the lightening process to optimize the amount of material that is removed. The lightening process removes material from both the external sides of each rotor and the internal ribbing and bearing support areas.

The Racing Beat machining process involves the installation of a snap ring between the rotor gear and the basic rotor to prevent the rotor gear from working away from the basic rotor at higher RPM. The ring gear is removed using a hydraulic press, and then an indexing groove is cut into both the rotor and the ring gear. A snap-ring is placed into the groove on the ring gear, and the assembly is placed into the rotor. Once the snap-ring expands into the groove on the rotor, the ring gear is permanently seated onto the rotor.

After completion of the machining process, we fully balance each pair of rotors with matching front and rear counterweights to provide an assembly capable of high RPM operation. As seen in the photo below, additional material is removed from the lower portion of each counterweight.

Each assembly includes two (2) super lightweight rotors, and one (1) front, and one (1) rear counterweight. Replacement rotors are available.
